RICHARD COVERT, OF BROOKLYN, NEW' YORK.

IMPROVED ARTIFICIAL LUMP-COAL.

Specification forming part of Letters Patent No. 48,372, dated J une 27, 1865.

tar, pitch, or artificial asphaltum, and dead or heavy oil, intimately mixed together by the aidof heat, and afterward aggregatedinto solid lumps by pressure by machinery or otherwise. The coal, if not fine enough, is ground, and gastar, pitch, or artificial asphaltum is mixed with it in any desirable proportions, dead or heavy I oil in suflicient quantity to permeate the entire mass, and the whole is then heated andstirred by machinery until it becomes thoroughly mixed and plastic. It is then by the same apparatus forced into molds and by heavy pressure united into solid lumps, after which it is ejected from the molds onto suitable endless bands, which carry itto any suitable receptacle.

I do not claim novelty in the combination of anthracite coal dust and powdered asphaltum.

Having thus described my in vention,I claim as new and desire to secure by Letters Patent- As a new article of manufacture, the artificial lump-coal, consisting of coal-dust, gas-tar, pitch, or artificial asphaltum, and dead or heavy oil, mixed by heat and stirring and aggreg'a ted by p ressure,as hereinbefore described.
